ILVI M f l JEM/afd @y @Maw @ya KATHERINE NICHOLS AND Patented Sept. 29, 1931 UNITED STATES PATENT OFFICE RICHARD BTTIEN, or CHICAGO, ILLINOIS; sAID BETTIEN AssIGNoR To SAID NioIIoLsv TELEPHONE Application iiled April 17,

rlhis inventionrelates to telephones ingeneral and particularly to telephones of the wall type which are usedin pay stations and booths.

The primary Object of the invention is to provide a telephone instrument which has a pair of properly spaced receivers which are rigidly connected to a transmitter and pivot# ally connected to the instrument base whereby the user is compelled to talk directly into the transmitter without coming in personal contact with it,` while the `receivers are arranged inV proper position relative to the head of the user.

Another object is to provide a new and novel telephone instrument which is provided with connected spaced receivers to which a transmitter is rigidly connected and comprising a single unit which is pivotally ias connected to a suitable support whereby the receivers and the transmitter, while remaining in constant position relative to each other, may be swung as a unit to various angular positions.

A still further object is to provide a new and novel method' of establishing the various electrical connections between the instrument and the line wires.

Numerous other objects and advantages will be apparent throughout the progress of the following specification.

Fig. 1 is a detail sectional view of the improved apparatus on the line 1-1 of Fig. 2.

Fig. 2 is a detail elevation showing the apparatus supported on a wall. A K

Fig. 3 is a detail sectional view onY the line 3 3 of Fig. 1.

Referring to the drawings, 5 designates a suitable base which is attaohed'to the wall and carries a housing 6. A tubular vsleeve or shell 7 is operatively connected to the house ing and is provided with slots 8, 8 throughV "are supported 'on a plate member 25. terminal plug. 24 has a series of bin-ding scr ws 26', Fig.` 3', through which the various land the line wires are` made.

193i. serial No. 530,867.

A transmitter 21 is rigidly connected tothe v coupling member 15 and is suitably spaced between the receivers 19. The normal space or positions of the two receivers is slightly less than the normal head width, and the leal springs. 18 tend to hold the receivers com iortably to the ears of a user when the instrument is in use. `The pivotal point 14 permits the receivers and the transmitter to be swung from down normal non-use position as shown in Figs. 1 and 4, "to operating or using position as shown in dotted lines in Fig. l. Y

The circuit wires from the receivers extend through the flexible conduits 2O and tubular arms 17 into the hollow body portion of the vcoupling member 15 where they are incorporated with the transmitter circuit wires to form a cord, V not shown. This cord passes through one of the tubular arms 13 and into the stud 10. The stud 10 is provided with an opening 22 through which the cord passes and leads inside of the housing 6 where it is operatively connected to the various elements arranged inside of the housing.

I These elements coniprise-aresistance coil 23, Fig. 1|, and a liber terminal plug 211 which The electrical connections between the instrument Contact plates 27 and 28 are fastened to the terminal plug 2l1-ior` completing the circuit, the contact plate 27 being elongated to extend across the path of the VstudlO. These Contact Vplates are included iii the signal circuit and when the instrument is in normal position, as shown Y it out of contact iwith its companion Contact 4 flu plate 28, thereby breaking the signal circuit.

In using the device, the receivers and the connecte-d transmitter are swung from the position shown in full lines to the position shown in dotted lines in Fig. l. The pins 9 are then pulled outwardly to the right, Fig. l, to move the stud l0 and permitting the cont-act plate 2T to engage the contact plate 28 to complete the circuit.

rI`he instrument may be used in connection with a coin box 3G having the usual coin receiving openings 3l. The coin box is preierably arranged between the receivers as shown in Fig. 2. The instrument may also be hooked up for dial operation, the dial being operatively connected to a part of the housing 6. rlhe connections to the coin box and to the dial are made in the usual manner so further description as to these electrical connections will not be made.

In operating the device, the receivers and the cooperating transmitter are swung from the position shown in tull lines to the position shown in dotted lines in Fig. l. The receivers are applied across the head oit a user when a co-in is inserted in the proper opening 3^. The insertion or" the coin makes the proper connection, and when the pins 9 are moved to the right, Fig. l, the circuit is completed between the plates 27 and 28. The number is then dialed on the dial 3Q.

Yhen the user has finished, the pins 9 are iorced inwardly, causing the liber tip Q9 on the stud 10 to move the lower contact plate 2 forwardly to the position shown in F ig. l, the receivers and transmitter being permitted to drop down in normal position as shown in full lines in Fig. l.

The invention provides a convenient and eliicient telephone device which causes the user to speak directly into the transmitter, but prevents direct contact therewith. The receivers are properly held in position on the head of the user, permitting the user to have free use of his hands tor dialing. The 'ilidable movement of the stud causes a positive and eilicient completion or breaking up ot the circuit.

Changes may be made in the form, construction, and arrangement of the various parts without departing from the spirit of the invention or sacriiicing any of its advanlcages, and the right is hereby reserved to make all such changes as fairly fall within the scope oi the following claims.

lIhe invent-ion is hereby claimed as follows:

l. In aI device of the class described, a unit con'iprising a pair of receivers, a transmitter operatively connected to the receivers, means for pivotally connecting said unit to a telephone housing, and manually operated means independent of the pivotal movement of the unit for controlling the signal circuit of the telephone system.

2. In a' device of the class described, a

housing, a pair of arms pivotally connected to the housing, receivers exibly connected to said arms, resilient mea-ns for holding the receivers in a predetermined spaced position, a transmitter iixed to said arms and spaced therebetween, said transmitter being movable with the arms, and means operating independently of the arms for controlling the signal circuit of a telephone system.

3. In a device of the class described, a housing, a receiver and a transmitter operatively connected to said housing, means inside of said housing for controlling the signal circuit of a telephone system, said means including a slidable plug and means for limiting the sliding movement of the plug and preventing removal thereof.

4. In a device of the class described, a housing, a. coupling member, arms fixed to said coupling member and pivotally connected to said housing, a pair of outwardly extending arms iixed to said coupling member, receivers flexibly connected to said last named arms, a transn'iitter arranged between said receivers and rigidly connected to said coupling member, and additional means operated independently of any of said other means for controlling the signal circuit of a telephone system.
